Therapy of advanced colorectal cancer with a combination of 5-fluorouracil, methyl-1,3-cis(2-chlorethyl)-1-nitrosourea, and vincristine

Abstract

In a randomized, controlled study of 80 patients with advanced colorectal carcinoma, the combination of 5-fluorouracil (5-FU), methyl-1, 3-cis(2-chlorethyl)-1-nitrosourea, and vincristine produced an overall degree to toxicity comparable to that of 5-FU used alone. At 10 weeks, a positive objective response rate of 43.5% was observed with the three-drug combination compared to 19.5% with 5-FU alone (P less than 0.5).
